When ever I remove or install an AppStore app, any hidden and white icons show up. Its annoying because I have to respring. This has happen in the past on certain jailbreakes but not on the 5.0 tethered jailbreak.

I have an iPhone 4, iPhone 3GS and iPad 2 on 5.0.1 and they all do this.

This is from a fresh restore and jailbreak, this time I tried Snowbreeze then the usual redsn0w. (See attachment)

You see this a lot when using cracked apps from either third-party apps or cydia. It could also be caused by a tweak you have installed that's not 100% compatible with your firmware. It's really hard to say for sure, I've always fixed it for people by restoring and going one tweak at a time until I find the one causing the issue.

To be honest I really don't keep track. Out of the 6 phones I'm around and maintain none of them do it. If one comes to me doing such things I just export their status file, restore and start installing going down the list I made (from status file) til it happens. Then I just leave that one out. It's really hard to just say its this tweak causing it, it just takes a little digging sometimes. Everybody's setup is a little bit different.
